Equipment)
Inspect and clean the air intake screen.
Booth Enclosure
Turn on the exhaust fan and vacuum the enclosure roof, walls,
and floor with a soft brush attachment. Wipe down the enclosure
with damp, lint-free cloths. Clean the booth exterior, all attached
equipment, and the spray room.
Check the panels for for cracks, damage and dirt. Clean dirt and
powder from the exterior. Seal any cracks or replace the panels.
Make sure the roof supports are secure.
Color Module
1. Start the exhaust fan and activate the pulse valves to blow off
as much powder as possible off the cartridge filters. Pump
the powder out of the color module.
2. Inspect the cartridge filter media and gaskets. Check the
interior of the cartridges for powder. Powder inside the
cartridges indicates leaking. Contamination of the media
indicates problems with the air filters or dryer. Replace the
filters if they are leaking or contaminated. Do not vacuum the
cartridge filters.
3. Disconnect the transfer hoses from the transfer pumps. Blow
the powder out of the hoses with compressed air. Remove
the transfer pumps and clean them as described in their
manuals. Remove and clean the pump adapters and pickup
tubes. Replace any worn parts.
4. Vacuum the color module interior. Check the fluidizing plates.
If they are stained, the air supply could be contaminated by
oil or moisture. Replace the fluidizing plates if they are
contaminated.
5. Check the pulse valves and nozzles, mouth gasket, limit
switch, clamping straps, and skirt seal. Replace any
damaged components.
Feed Hoppers
Remove the powder from the hopper. Vacuum the interior.
Check the fluidizing plate. If the plate is stained, the air supply
could be contaminated by oil or moisture. Check the air dryer
and air filters. Replace the fluidizing plate if it is contaminated.
Powder Spray Guns and Cables
Clean the spray guns. Perform electrostatic resistance checks
as described in the spray gun and gun control unit manuals.
Powder Pumps and Feed Hoses
Disassemble the pumps and clean them according to the
instructions in their manuals. Replace any worn or damaged
